Materials and Methods
As part of a large study evaluating the basilar thumb joint and associated demographics, we prospectively enrolled 163 volunteers, divided equally among 3 age groups (age 18–39 y, 40–59 y, and 60 y and older). Volunteers were recruited both internally and externally at a university medical center and consisted of a mixture of students, employees, and retired individuals who responded to advertisements placed at local stores and residential facilities. For each, a single examiner conducted an
Results
The study group consisted of 81 men and 82 women, with an average age of 48 years (range, 20–83 y). Subjects were evenly divided by age group and gender into the 3 age groups. The average Beighton score was 2 (range, 0–9). Forty subjects had Beighton scores of 4 or greater. The average stress view ratio was 0.31 (range, 0.06–0.58) (Fig. 2). For the total sample (n = 163), younger age was correlated with an increased Beighton score (r = −0.256, p = .001) and a higher stress view ratio (r =
Discussion
Eaton and Littler12 and Lane and Eaton15 originally described the concept of joint laxity as a factor in the development of osteoarthritis of the TM joint and noted hypermobility of the TM joint as an idiopathic condition leading to painful synovitis and early arthritis of the joint. The anatomic studies of Pellegrini et al4, 16 showed that attrition or insufficiency of the anterior oblique ligament, considered a major stabilizer of the TM joint, caused abnormal biomechanical loading that was
